I have some k8s jobs that make various http requests to other pods in the cluster.
I have very limited control over these job manifests but I can enforce a label etc
I need to insert some request headers into the http requests the jobs invoke… Is this possible with isio…I saw rules/handlers in IstioOldie 1.4 but not sure if this the approach . or would an envoy filter be the correct place??
*note these jobs have no virtual service…
basically i want to do something along these lines…
kind:istio-headers-injection-by-label
spec
selector: my-job-known-label
template:
request-headers:
- add
header1: "blob"
header2: "blob2"
